AIM:To investigate the effectiveness of insulin on decreasing serum potassium concentration during anhepatic stage of orthotopic liver transplantation. METHODS:Sixteen patients with serum potassium concentrations greater than 4.0 mmol/L at the onset of anhepatic stage were randomized into two groups.The patients in control group (n=8) received no treatment, while those in treatment group (n=8) received an intravenous bolus injection of regular insulin (20U) 10 min into the anhepatic stage,followed by a glucose infusion (500mL 50g/L dextrose) over 15 min. RESULTS:In control group,potassium concentration underwent no changes whereas in treatment group,it decreased from 4.8±0.48 mmol/L to 4.19±0.55 mmol/L (mean±SD) within 15 min and to 3.62±0.45 mmol/L 60 min after the therapy.The potassium concentration was lower in treatment group than in control group within 30 min of treatment (3.94±0.57 vs 4.47±0.42 mmol/L, respectively;P<0.05),and increased similarly 30 s after graft reperfusion in both groups of patients,but remained lower in treatment group (5.81±2.78 vs 7.44±1.75 mmol/L, respectively;P<0.05).The potassium concentration returned to pre-reperfusion levels within 5 min after graft reperfusion. CONCLUSION:In patients undergoing orthotopic liver transplantation,the administration of insulin rapidly decreases serum potassium concentration even in the absence of the liver,suggesting an important contribution by extrahepatic tissues in insulin-stimulated uptake of potassium. 展开更多

Persistent hyperinsulinemic hypoglycemia is caused most commonly by an insulinoma in adults or by nesidioblastosis in neonates. In adults, nesidioblastosis is a rare disorder characterized by diffuse or disseminated proliferation of islet cells. We recently encountered a case of nesidioblastosis in an adult. A 71-year-old man was admitted due to intermittent general weakness, abdominal pain, and mild dyspnea. The patient underwent a subtotal gastrectomy for a gastric adenocarcinoma two years ago. After 5 d of admission, the patient showed symptoms of cold sweating, chilling, and hypotension 30 min after eating. Thereafter, he frequently showed similar symptoms accounting for hypoglycemia regardless of food consumption. Laboratory findings revealed a low fasting blood glucose level (25 mg/dL), and a high insulin level (47 μIU/mL). Selective intra-arterial calcium stimulation with hepatic venous sampling (ASVS) was performed to localize a mass and revealed an increased insulin level about fourfold that of the normal fasting level at 60 s in the splenic artery, which suggested the presence of an insulinoma in the tail of pancreas. A distal pancreatectomy was performed. Neither intraoperative exploration nor a frozen biopsy specimen detected any mass-forming lesion. On the histological examination, many of the islets were enlarged and irregularly shaped in all specimens, the arrangement of which was a Iobulated islet pattern. Cytologically, a considerable subpopulation of endocrine cells showed enlarged and hyperchromatic nuclei. By immunohistochemistry, the cells were identified as p-cells. These clinical, radiological, microscopic and immuno-histochemical findings are consistent with diffuse nesidioblastosis in adults. 展开更多
